Abstract
What is the Critique of Pure Reason about? The terminology of the work is so perplexing, its argument so obscurely expressed, that the ordinary reader may be forgiven if he puts it down at the end very much in the dark as to what it all means. He will have seen that in it Kant has attempted to establish certain conclusions: the subjectivity of space and time, the existence and objective validity of a number of a priori concepts or categories, the falsity of the arguments used to defend the metaphysical system most widely favoured in German learned circles in the eighteenth century; but though he has grasped all this he may yet have failed to make sense of the work as a whole. It is the old story of not seeing the wood for trees; and in this case the fault is more excusable than in most, for the individual trees each demand so much attention and are so difficult to get round that it is all too easy to forget the very existence of the wood. At the worst, one may think that there is no wood at all; only a miscellaneous aggregate of individual trees which have nothing to do with each other.
